Why Polish Your Pontoon Boat?

Polishing your pontoon boat is not just about aesthetics. It’s about preserving the life of your boat. Over time, the aluminum pontoons of your boat can become dull and tarnished due to exposure to water, sun, and other elements. This can lead to corrosion and damage, affecting your boat’s performance and longevity.

Polishing your pontoons can help protect them from these elements, giving them a mirror-like finish that looks great and helps prevent damage. It’s an investment in your boat’s future and something all boat owners should consider regularly doing.

What You’ll Need

Before we start polishing, let’s gather all the necessary materials. You’ll need the following:

  • A cleaner: This is used to prepare the pontoons for polishing. Many cleaners are available on the market, but a product specifically designed for pontoon boats is best. Avoid using home products like dish soap, which can erode the polymers on your boat. Star Brite Cleaner is a popular choice among pontoons.
  • A buffer: This buffs the pontoons before applying the polish. A variable speed buffer like the DeWalt is a good option.
  • A polisher: This is used to give your pontoons a shiny, mirror-like finish. The Shark Hide Aluminum Pontoon Boat Polish is a favorite among many boat owners.
  • A protectant: This is used to protect your pontoons after polishing. The Shark Hide Metal Protectant is a great choice.

Step-by-Step Guide to Polishing Your Pontoon Boat

Step 1: Prepare the Pontoons

Before you start polishing, it’s crucial to prepare the pontoons. This involves a thorough cleaning to remove any algae or buildup. If your boat has been docked or at the marina for extended periods, there’s likely to be some buildup.

Start by using a pressure washer to clean the pontoons. A simple pressure wash with water should remove most of the visible buildup. You can use a cleaner like the Star Brite Cleaner if there’s stubborn grime or dirt. Apply the cleaner to the pontoons and scrub with a brush or a wool pad.

Remember, it’s essential to be gentle during this process. Avoid being too overzealous, as it can lead to circle marks on the aluminum. It’s best to wipe in the direction of the grain to avoid scratching the surface.

Step 2: Buff the Pontoons

Once the pontoons are clean, it’s time to buff them. This step is optional but can help give you the best results.

Use a variable speed buffer to buff the pontoons. This will help to smooth out any imperfections and prepare the surface for the polish.

Step 3: Apply the Polish

Now it’s time to start polishing. Apply a small amount of the Shark Hide Aluminum Pontoon Boat Polish to a wet rag and apply it to the pontoons. It’s best to work in small sections to ensure that the polish is applied evenly.

Remember, polishing is not a race. Take your time and make sure you cover every inch of the pontoons. The more thorough you are, the better your results will be.

Step 4: Rinse and Repeat

After you’ve applied the polish, rinse it off with water. Then, take a look at your pontoons. You can repeat the process if they’re not as shiny as you’d like. Some boat owners find they get the best results by applying two or three coats of polish.

Step 5: Protect Your Pontoons

The final step is to protect your newly polished pontoons. Apply a protectant like the Shark Hide Metal Protectant to the pontoons. This will help seal the polish and protect the pontoons from the elements.

Step 6: Regular Maintenance

Once you’ve polished your pontoon boat, it’s important to maintain it regularly to keep it looking its best. This includes cleaning it regularly, applying a protectant to the pontoons, and polishing them as needed. Regular maintenance can help extend your boat’s life and keep it looking its best.

Step 7: Learn from the Experts

To ensure you’re getting the best results, it’s always a good idea to learn from those who have done it before. Numerous online resources can provide additional tips and tricks for polishing your pontoon boat.

Common Mistakes to Avoid When Polishing Your Pontoon Boat

When it comes to polishing your pontoon boat, there are a few common mistakes that can hinder your efforts and potentially cause damage to your boat. Here are some of the most common ones to avoid:

  1. Using the Wrong Products: Not all cleaning and polishing products are suitable for pontoons. Using the wrong product can lead to ineffective cleaning, damage to the pontoon’s surface, or even corrosion. Always ensure that the products you use are specifically designed for use on pontoons.
  2. Overzealous Buffing: While it’s important to buff your pontoons to prepare them for polishing, being too aggressive can cause damage. Overzealous buffing can lead to circle marks on the aluminum or even scratch the surface. Always buff gently and in the direction of the grain.
  3. Skipping the Rinse: After applying the polish, it’s crucial to rinse it off thoroughly. Failing to do so can result in a sticky residue that attracts dirt and grime. Always rinse thoroughly after polishing to ensure a clean, shiny finish.
  4. Neglecting Regular Maintenance: Polishing your pontoon boat is not a one-time task. Regular maintenance, including cleaning and applying a protectant, is necessary to keep your boat looking its best and to protect it from the elements. Neglecting regular maintenance can lead to dull, tarnished pontoons and a shorter lifespan for your boat.
  5. Ignoring Safety Precautions: Using various chemicals and tools involves polishing a pontoon boat. Ignoring safety precautions can lead to accidents or injuries. Always wear appropriate protective gear, work in a well-ventilated area, and store your products safely.

By avoiding these common mistakes, you can ensure that your pontoon boat remains in top condition and continues to shine brightly for years.


Polishing your pontoon boat is more than just a cosmetic enhancement. It’s a crucial maintenance task that safeguards the longevity of your boat, protects it from the elements, and ensures optimal performance. With the right products, patience, and regular maintenance, you can maintain a mirror-like finish on your pontoons, making your boat look its best and extending its lifespan.
